RESUMO

INTRODUCTION: With the advent of the pandemic in 2020 and the lack of perspectives on the treatment of COVID-19, numerous therapeutic proposals have emerged, including hydroxychloroquine and azithromycin. Therefore, some studies have shown that in many countries, the demand for azithromycin has increased during the pandemic. In Brazil, antibiotics can only be purchased with a medical, dental, or veterinary prescription. This study aimed to determine whether the number of prescriptions made by veterinarians (which could be used by humans) has increased during the pandemic. METHODOLOGY: Data on the purchase of antibiotics made under veterinary prescriptions in Brazilian pharmacies between 2014 and 2021 were collected. To assess the changes in monthly trends in the use of the selected antibiotics, we applied the Joinpoint regression. RESULTS: The most prescribed antibiotic in all years was cephalexin (35%), followed by amoxicillin (24%). During the pandemic, sales of azithromycin substantially increased. Regression analysis showed that since 2014, azithromycin prescriptions grew by an average of 0.67% per month. At the beginning of the pandemic, the monthly growth rate became 12.64%. When comparing azithromycin sales during the pandemic with the historical average (2014-2019), the increase was 41%. CONCLUSIONS: During the pandemic, there was no animal health situation in Brazil that required the use of this antibiotic. Veterinary prescriptions may have been an instrument for human access to azithromycin for the treatment of COVID-19. Stricter enforcement policies are needed to address this problem to avoid antimicrobial resistance.

RESUMO

During the COVID-19 pandemic, people worldwide, including the scientific community, were insecure and fearful. The lack of vaccines at the beginning of the pandemic and the high mortality rate led to a search for alternative treatments for COVID-19. Among these proposals, a postulated activity of azithromycin was frequently studied in early treatment. In view of this, many countries saw an increase in the consumption of this antibiotic. Thus, the objective of this study was to evaluate, in Brazil, whether there was an increase in azithromycin prescriptions made by dentists, as they may have been prescribing this antibiotic as a probable treatment for COVID-19. This is an interrupted time series that analyzed antimicrobial prescriptions data between January 2014 and July 2021. The data were taken from the National System of Controlled Products Management, and pre- and postpandemic periods were compared. To assess changes in azithromycin consumption, Joinpoint regression and analysis of variance, followed by Dunnett's test, were used. More than 38 million prescriptions written during the period were analyzed. Amoxicillin (72.3%), azithromycin (18.0%), cephalexin (6.1%), and metronidazole (3.58%) were the most prescribed antibiotics. At the beginning of the pandemic, there was a drop in amoxicillin prescriptions motivated by a decrease in consultations, but conversely, in less than three months, azithromycin prescriptions grew by more than 100%. The exaggerated use of this antibiotic during the pandemic will certainly have consequences in the short and medium term on indicators of bacterial resistance. The use of guidelines and respect for the therapeutic protocols of government agencies should be fundamental for collective and strategic action in the fight against health emergencies.
